I've read posts here from people who swear by separate amps along with a regular receiver. My local dealer only had an Onkyo 282 amp (two channel, 120 watts per channel) that I could demo. I took it home and haven't been impressed with it. I think I prefer the sound of my receiver's amp, rated at 110 watts per channel. Maybe I just need to buy a better amp to hear more of a difference? Problem is, I don't want to spend more than say, $500. I have two questions. One: Do you think I could improve upon the sound of my 3802 with a separate amp for one or more channels, costing around $500? Two: I've heard that going to a separate amp for one or more channels helps lesson the load on the receiver for the remaining channels. Is this true? If it is true, doesn't it imply that I will somehow be lessoning the sound quality by adding more speakers, such as in a 6.1 or 7.1 setup, because they will be making my receiver work harder? Or does the receiver simply put out a given amount of wattage per channel? Any input appreciated.
